paragraph 2.B.2., at the latest by December 31, 2009. 

Revision 1 affects compliance with Revision 0 of this ALERT SERVICE BULLETIN. 

Revision 1 of this ALERT SERVICE BULLETIN formed the subject of EASA Airworthiness Directive 

No. 2009-0178-E. 

Revision 2:

To extend the deadline for compliance with the instructions concerning the installation of the hoist 

beam lower protector, previously set at December 2009, until June 30, 2011 for SUPER PUMA 

helicopters equipped with a RH side sliding door P/N 332A22-1165-01 and for PUMA helicopters. 

To delete SA330 helicopter versions F and G from this ALERT SERVICE BULLETIN following the 

withdrawal of the Type Certificate. 

Revision 2 does not affect compliance with Revision 1 of this ALERT SERVICE BULLETIN. 

Revision 2 of this ALERT SERVICE BULLETIN formed the subject of EASA Airworthiness Directive 

No. 2009-0271, except for the limit date for installation of the hoist beam lower fitting protector set at 

June 30, 2010 in the EASA directive and set at June 30, 2011 in this ALERT SERVICE BULLETIN. 

Revision 3:

The purpose of Revision 3 of this ALERT SERVICE BULLETIN is: 

- to take into account improved procedures for the installation of the hoist beam lower fitting protector 

on SUPER PUMA helicopters not equipped with a RH side sliding door P/N 332A22-1165-01 

(paragraph 2.B.2.b. of this ALERT SERVICE BULLETIN). 

- to enable the embodiment of new modifications for the installation of a hoist beam lower fitting 

protector for SUPER PUMA helicopters equipped with a RH side sliding door P/N 332A22-1165-01 

(MOD 0726676 as per paragraph 2.B.5 of this ALERT SERVICE BULLETIN) and for all PUMA 

helicopters (MOD 0727216 as per paragraph 2.B.4 of this ALERT SERVICE BULLETIN). 

The installation of these modifications, which are now made mandatory before July 31, 2011, by 

Revision 3 of this ALERT SERVICE BULLETIN, makes it possible to cancel the limitations 

specified in paragraph 2.B.1. and 2.B.3. and which are still in force for these helicopters. 

- to delete SA330 helicopter versions C, H and Ea from the effectivity of this ALERT SERVICE 

BULLETIN: 

. following the Information Notice No. 2207-I-00, the versions C and H are not maintained, 

. following new investigations, it turns out that the hoist beams specified in paragraph 1.A. are not 

defined for version Ea. 

Revision 3 does not affect compliance with the previous revisions of this ALERT SERVICE 

BULLETIN. 
Approved under EASA DOA No. 21J.056 Page 5/36 

 2011.07.06

Revision 3 of this ALERT SERVICE BULLETIN will form the subject of an EASA Airworthiness 

Directive, except for the limit date for installation of new hoist beam lower fitting protectors, which is 

now set at July 31, 2011 in this ALERT SERVICE BULLETIN, but which will remain unchanged in the 

new EASA Airworthiness Directive with respect to EASA Airworthiness Dirctive No. 2009-0271. 

1.D. DESCRIPTION 

Revision 0:

EUROCOPTER has received a report of hydraulic hoist cable jamming at the hoist beam lower fitting (a) 

(double hoist plate installation - zone Z shown on photo 4). The jamming occurred during a hoisting 

operation at sea, during the cable raising phase while the load was swinging heavily. 

As the helicopter was fitted with an auxiliary electric hoist, it was possible to complete the hoisting 

operation. 

During the investigations conducted by EUROCOPTER following this event, three conditions were 

identified which could jeopardize safety: 

1) For all the helicopters mentioned in paragraph 1.A.1.: 

Operating the hoist control in the up or down direction after the main hoist cable has jammed in zone 

Z (shown on photos 3 and 4) can lead to the failure of this cable due to mechanical chafing on the 

fitting. 

To correct this condition, which could jeopardize safety, this ALERT SERVICE BULLETIN renders 

compliance with the hoisting instruction defined in paragraph 2.B.1. mandatory. 

For SUPER PUMA helicopters: This ALERT SERVICE BULLETIN makes the installation of a hoist 

beam lower fitting protector mandatory, in order to cancel this hoisting instruction. 

NOTE 5 

This hoist beam lower fitting protector is incompatible 

with SUPER PUMA helicopters equipped with a RH 

side sliding door P/N 332A22-1165-01 as it would 

prevent this door type from opening. Another protector 

for these helicopters will be proposed at part of a 

subsequent revision to this ALERT SERVICE 

BULLETIN. 

For PUMA helicopters: To cancel this hoisting instruction, a protector will be proposed to you in a 

subsequent revision of this ALERT SERVICE BULLETIN. 

NOTE 6

The protector defined for 

SUPER PUMA helicopters cannot be installed on 

PUMA helicopters as it would prevent the door from 

opening. 
Approved under EASA DOA No. 21J.056 Page 6/36 

 2011.07.06

2) For helicopters mentioned in paragraph 1.A.1., fitted with an auxiliary electric hoist whose electrical 

power supply harness is located in zone Z, shown on photo 3: 

There is a risk of interference between the hydraulic hoist cable and the auxiliary hoist electrical 

harness, which can lead to damage to this electrical harness and cause a short circuit when the 

auxiliary hoist is energized. This short circuit can cause the main hoist cable to melt and fail. 

To correct this condition, which could jeopardize safety, this ALERT SERVICE BULLETIN makes the 

installation of a hoist beam lower fitting protector mandatory. Pending installation of this protector, 

this ALERT SERVICE BULLETIN renders compliance with the hoisting instruction defined in 

paragraph 2.B.1. mandatory. 

The double and single hoist installations are shown respectively on photos 1 and 2. 

Revision 1:

3) For helicopters, mentioned in paragraph 1.A.1., not fitted with the hoist beam lower fitting protector 

and on which the hoist control electrical harness is routed in zone Z, shown on photo 3. 

In this configuration, the hoist cable may cause damage to the hoist pyrotechnical squib firing control 

electrical harness and thus cause untimely firing of the pyrotechnical squib. 

To correct this condition, which could jeopardize safety, Revision 1 of this ALERT SERVICE 

BULLETIN makes the removal of the squib and installation of two placards (in the cockpit and cabin) 

mandatory, pending installation of the hoist beam lower fitting protector. 

Revision 2:

For industrialization reasons, the components comprising the definition of the hoist beam lower fitting 

protector for SUPER PUMA helicopters equipped with a RH side sliding door P/N 

332A22-1165-01 and for PUMA helicopters, cannot be developed and therefore not be installed before 

December 31, 2009. Consequently, for these helicopters, the limitations defined in paragraph 2.B.1. 

and 2.B.3. of this ALERT SERVICE BULLETIN are extended until June 30, 2011, to enable a hoist 

beam lower fitting protector to be installed. 

Revision 3:

The hoist beam lower fitting protectors for SUPER PUMA helicopters equipped with a RH side sliding 

door P/N 332A22-1165-01 and for PUMA helicopters have been defined. 

To cancel the hoisting instructions defined in paragraph 2.B.1. and 2.B.3., Revision 3 of this ALERT 

SERVICE BULLETIN renders the installation of a hoist beam lower fitting protector mandatory on all 

helicopters specified in paragraph 1.A.1., at the latest by July 31, 2011.

POSSIBLY SUBSEQUENT TO THE CABLE 

SWINGING HEAVILY, DO NOT OPERATE THE 

HOIST CONTROL, NEITHER IN THE UP OR DOWN 

DIRECTION, TO REDUCE THE RISK OF DAMAGING 

THE CABLE, WHICH COULD CAUSE IT TO FAIL. 

- Make a placard with the following wording (red text on white background) and affix it in a visible 

position, near the hoist operator station: 

IF THE CABLE JAMS IN THE HOIST BEAM LOWER

CHAPTER 4 

"Normal Procedures" (approved part)

The hoist cable cannot be cut using the PILOT’s and COPILOT’s control, it is therefore mandatory 

before any hoisting mission, to make sure that the radio-communication between the pilot and the 

hoist operator is of good quality in the flight conditions (before performing any hoisting operation), and 

that the hand shears are within the reach of the hoist operator. 

Appendix 1
